Description :

　　1、 8000D portable water quality proportional sampler instrument description:

　　The instrument complies with the Chinese Ministry of Environmental Protection's HJ/T 372-2007 "Technical Requirements and Testing Methods for Water Quality Automatic Samplers". It is a multifunctional environmental monitoring instrument that integrates flow measurement, water sample collection, automatic bottle separation, and constant temperature refrigeration. It has the characteristics of small size, easy mobility, simple operation, environmental protection, and energy saving. Suitable for environmental monitoring stations, supervisory agencies, research institutes, water affairs, municipal and sewage treatment plants at all levels, automatic sampling of water samples from industrial pollution source discharge outlets, rivers, lakes, seas, etc.

　　2、 The main functional features of the 8000D portable water quality proportional sampler are:

　　1. By using an input type liquid level sensor or ultrasonic sensor, flow measurement and liquid level measurement can be achieved, completing proportional, timed, fixed flow, liquid level proportional, and quantitative sampling;

　　2. Suitable for flow measurement of industrial pollution source discharge outlets for various types of weirs and channels such as triangular weirs, rectangular weirs, equal width weirs, and Bacher troughs;

　　3. High reliability peristaltic pump, hybrid stepper motor subdivision drive, smooth and reliable operation, easy to disassemble pump head, pollution-free liquid and pipeline contact, high temperature resistance, and corrosion resistance;

　　4. Modular program structure, multi CPU control circuit, programmable control, optoelectronic isolation, improve the overall performance of the product;

　　5. Liquid flow detector, automatically completes the cleaning and emptying of the sampling port and pipeline, ensuring the collection of qualified water samples;

　　6. Mechanical distribution arm sampling photoelectric control, subdivision drive stepper motor, accurate and reliable automatic positioning for packaging, can set bottle separation mode, complete single or mixed collection;

　　7. Humanized program design, rich human-machine dialogue interface, Chinese LCD display, easy and fast operation;

　　8. Environmentally friendly and energy-saving refrigeration system, low power consumption, good insulation and refrigeration effect;

　　9. Built in high-capacity rechargeable battery pack, suitable for both AC and DC use.
